在这两种情况下我都无法安装 npm 请指导我谢谢

Answer 1

因为我还不能评论..

您需要运行方法 2，因为 root 这就是您收到 EACCES 错误的原因

sudo curl -L https://npmjs.com/install.sh | sudo sh

Answer 2

应该使用 NVM。

第一个运行

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.25.1/install.sh | bash

之后

nvm install 0.12

这将为您提供工作节点。如果您想了解更多关于 nvm 的其他优势 - 请在 https://github.com/creationix/nvm
